A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A computer-implemented system may include an electromechanical machine configured to be manipulated by a user while the user performs a treatment plan, an interface comprising a display configured to present information associated with the treatment plan, and a processing device configured to receive, from one or more data sources, information associated with the user, wherein the information comprises one or more risk factors associated with a cardiac condition or a cardiac outcome, generate, using one or more trained machine learning models, the treatment plan for the user, wherein the treatment plan is generated based on the information associated with the user, and the treatment plan comprises one or more exercises associated with managing the one or more risk factors in order to reduce a probability of a cardiac intervention for the user, and transmit the treatment plan to cause the electromechanical machine to implement the one or more exercises.

There is disclosed a system for engaging in exercise. The system includes a communications interface for receiving instructions from control software controlling operation of the exercise device, a resistance device for generating resistance to the exercise and applied to the exercise device, the resistance device for increasing or decreasing resistance for the exercise under control of the control software, and the control software operating to generate a simulated haptic movement, using the resistance device, by temporarily altering the resistance applied to the exercise device by the resistance device.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

A golf club head includes a body having a recessed channel formed in an outer surface. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending at least partially over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight is slidably engaged with the cover and the cover is positionable in at least an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is selectively slidable within the recessed channel, and a locked configuration whereby the cover is at least partially disposed within the recessed channel and the weight is secured within the recessed channel. The weight moves with the cover between the unlocked configuration and the locked configuration.

A light field (LF) display system for displaying holographic content (e.g., a holographic sporting event or holographic content to augment a holographic sporting event) to viewers in an arena. The LF display system in the arena includes LF display modules tiled together to form an array of LF modules. The array of LF modules create a holographic object volume for displaying the holographic content in the arena. The array of LF modules displays the holographic content to viewers in the viewing volumes. The LF display system can be included in a LF sporting event network. The LF sporting event network allows holographic content to be created at one location and presented at another location. The LF sporting event network includes a network system to manage the digital rights of the holographic sporting event content.

A speed control system and method for controlling the speed of an endless belt loop of a treadmill. The speed control system comprises a plurality of image sensors, each image sensor configured to take an image of a user of the treadmill; and a controller configured to control the speed of the endless belt loop by (a) receiving the images of the user taken by the image sensors, (b) rectifying the images based on a calibration of the image sensors, (c) comparing the images to form a disparity map, (d) determining a distance of a user of the treadmill relative to the treadmill using the disparity map, and (e) calculating velocity or acceleration of the treadmill based on the determined distance of the user.

Disclosed are various embodiments of a golf training system. In one non-limiting example, a system includes a feedback device, a sensor, and a computing device. The computing device is configured to at least receive sensor data from the sensor during the golf swing of the user and identify a plurality of body movements in which each respective body movement corresponds to a stage of a golf swing sequence based at least in part on the sensor data. The computing device can also be configured to activate a plurality of feedback indicators according to the golf swing sequence for feedback to the user during the golf swing.

A golf swing trainer includes a first tube with a first attachment arm that extends therefrom; a second tube at least partially telescoped into the first tube, the second tube having a second attachment arm that extends therefrom; a fourth attachment arm coupled to the first attachment arm for securing the first tube to a shaft of a golf club; a fifth attachment arm coupled to the second attachment arm for securing the second tube to the shaft of the golf club; and a weight movable within the first tube and the second tube. A method for pause drill training includes attaching a golf swing trainer to a shaft of a golf club such that a weight within the golf swing trainer is freely movable within a first tube and a second tube, the second tube at least partially telescoped into the first tube.

A force measurement system is disclosed herein. The force measurement system includes a force measurement assembly configured to receive a subject, and one or more data processing devices operatively coupled to the force measurement assembly. In one embodiment, the one or more data processing devices are configured to determine a difference between a center of pressure and a center of mass for the subject from output force and/or moment data, and to determine the fall risk of the subject based upon the difference between the center of pressure and the center of mass for the subject. In another embodiment, the one or more data processing devices are configured to determine one or more balance parameters of the subject from the output force and/or moment data while the subject is stepping onto the top surface of the force measurement assembly and/or stepping off the top surface of the force measurement assembly.
